Question

Practice problem (Zero exponents problem)

x^0
15^0
2n^0
-3a^0

Answer 1

For any non-zero number or variable raised to the power of zero, the result is always 1. Here's how that looks for each of the expressions you provided:

1. \( x^0 = 1 \) (as long as \( x \neq 0 \))
2. \( 15^0 = 1 \)
3. \( 2n^0 = 2 \cdot 1 = 2 \) (as long as \( n \neq 0 \))
4. \( -3a^0 = -3 \cdot 1 = -3 \) (as long as \( a \neq 0 \))

So the results are:
- \( x^0 = 1 \)
- \( 15^0 = 1 \)
- \( 2n^0 = 2 \)
- \( -3a^0 = -3 \)

If the bases are non-zero, the calculations yield these results.
